Ionic mobility of which of the following 2nd group metal ions is maximum in aqueous solution? (1) Mg2+(2) Ca2+(3) Sr2+(4) Be2+ |
|
Answer» Correct option is (3) Sr2+ Smaller the size of ion greater is it's hydration & greater is it's hydrated radii & smaller is ionic mobility. So order of ionic mobility: Be2+ < Mg2+< Ca2+ < Sr2+ < Ba2+ |
